You need to use PREPARE to do a dynamic SQL or EXECUTE IMMEDIATE and build
the string like this:

Eval mySQL = 'UPDATE ' + R1EFIL + ' SET ' + R1EFLD + '=' + R1EFVL + ' WHERE
INUMBR = ' + M1SSKU

/EXEC SQL
C+ EXECUTE IMMEDIATE :mySql
/END-Exec

Or something like that.

0001.11 c/Exec Sql 
0001.12 c+ Update :R1EFIL 
0001.13 c+ set :R1EFLD = :R1EFVL 
0001.14 c+ where INUMBR=:M1SSKU
0001.15 c/End-Exec 

This is what I would like where :R1EFIL contains the value 'INVMST' ,
:R1EFLD='BYRNUM' and :R1EFVL = 21, INUMBR is field in :R1EFIL (INVMST) and
:M1SSKU = (example) 888

That is I would update record with SKU#=888 in file INVMST setting the
BYRNUM field to 21

Keying in program gives me invalid token at the : in R1EFIL and R1EFLD, am I
missing something (besdies my sanity that is?)

You have two choices, the grunt way, as you've described it already in your
original note, and to use SQL and build the select statement, something
like:
SELECT EFV FROM INVMST into :BUYR

I recently worked on trying to create the following:

Eval BUYR = GetFieldValue('EFV')

However, programmically it isn't known how to do that with RPG IV and the
ILE environment, aside from using SQL or some other dynamic query tool.

Subject: Populating fields based on field name in a file

I have a "rules" file whichcontains the following fields:

MFD - master field name (a field name in file MMST)
MFV - value for field name above 
EFL - environment file name (could be 1 of 7 for example INVMST)
EFD - environment field name (field name from file named above i.e. DEPT)
EFV - environment field value (value for field name above)

the user selects a record in the MMST file (ie. SKU: 12345) and it shoudl
then populate based on the rules each fo the fields/values in the
appropriate environment file:

Example:

Rules file:

MFD=CORG
MFV=US
EFL=INVMST
EFD=BUYR
EFV=123
So if the CORG field='US' in the SKU record selected from the MMST file I
want the BUYR field in INVMST to be set to 123

What I have "tentatively" done (and I don't like it) is shown as a "small
snippet" below, FYI In the MMST file I have 20+ fields and I have (as of
right now) 7 environment files which have multiple (5-50 approx. fields)

IF MFD='CORG' and CORG (a fld in MMST) = MFV and EFD='BUYR'
eval BUYR=EFV
endif

My "befuddled" mind right now sees that I would ahve to this the above for
EVERY field in in every file??

Gotta be an easier way???????????//
